Burglars smashed their way into the 'Rehab' singer's North London property at 4am this morning (30.01.09) - stealing £15,000 worth of her belongings including recording equipment and five guitars - just a couple of days before the singer returns to the UK from the Caribbean island of St Lucia.

A source said: "Amy is devastated. Some of the guitars are irreplaceable due to their sentimental value. The flat is in a real state. It had been cleaned up in preparation for her return."

Police say there are, as yet, no leads in their bid to find the culprits.

A police spokesperson said: "No arrests have been made and our enquiries continue."

Amy, 25, is expected to fly back to London this weekend to start work on her third album, the follow-up to the worldwide hit 'Back to Black'.

She is also set to visit her husband in prison in a bid to stop him filing for divorce.

The troubled star has applied to see Blake Fielder-Civil - who is serving a 27-month sentence for perverting the course of justice and grievous bodily harm - to try and convince him not to end their union of her alleged infidelity.

Amy has been romantically linked to 21-year-old actor Josh Bowman and a fitness instructor named Andrew while holidaying in St. Lucia.
